Abstract
Abrasive articles comprising precisely shaped particles are disclosed. The particles are bonded together to form a shaped mass, e.g., a wheel; alternatively, the particles can be bonded to a backing to form a coated abrasive article; or the particles can be bonded into a fibrous, nonwoven substrate to form a non-woven abrasive article.
Claims15
An abrasive article comprising a plurality of precisely shaped composites and a bonding medium wherein said precisely shaped composites comprise
- (a) a plurality of abrasive grits and
- (b) a polymeric binder, said binder formed by exposing a free radically polymerizable binder precursor to radiation energy,
- wherein said precisely shaped composites are bonded together by means of said bonding medium to form a shaped mass or wherein said precisely shaped composites are distibuted within a non-woven web and bonded to the web fibers by means of said bonding medium.
